Getting a LicenseException when using IUPACNamingPlugin

Hi all,

 This is my first post on the forum. I have installed Marvin Sketch and the corresponding marvin beans from Java. I have managed to import a simple SD file and convert it into Smiles, Inchi and other formats but I'm having problems with IUPACNamingPlugin. I initialize a new plugin as follows:

IUPACNamingPlugin pl = new IUPACNamingPlugin();

then, I simply do a:

pl.setMolecule(molecule);
pl.run();            
System.out.println(pl.getPreferredIUPACName());

and although naming runs from within the GUI, from Java it throws the following exception:

Exception in thread "main" chemaxon.license.LicenseException: No valid license has been found.
Product name: Structure to Name Plugin

Additionally, I have installed all necessary licenses as to be able to run Marvin Sketch and, indeed, when using the GUI everything goes like clockwork.

Any suggestions?

You don't need a license to use this functionality in MarvinSketch, but it requires "Structure to Name" license to run it in batch mode or via API. Please contact sales _at_ chemaxon.com if you want to obtain a license or if you have any questions about licenseing.
